This is a first step towards separating all transitions from the property descriptions. If we link the property descriptions from the transition object, this will in allow the descriptor array (property descriptions) to become immutable.

- Extend HValue interface to allow splitting observed input representation (comming from type feedback) from required input representation (dictated by instruction itself). Currently all instructions except for bitwise binary operations have this representations match. For bitwise binary operations hydrogen builder unconditionaly forces Integer32 representation for those operations that have Double type feedback. Thus causing representation inference to incorrectly count such uses as Integer32 instead of Double. This change also prepares for more fine grained type feedback for inputs of binary operations.

- For phies that are not convertable to Integer32 discard direct and indirect use count of Integer32 type to avoid propagation of these uses to connected phies.

The serialized node structure currently holds an index
of its first containment edge in the edges array.
The index can be quite big (up to 7 digits for large snapshots).
The patch changes the serialization format to pass
node containment edge count instead. For most nodes the count
is just a single digit number.
This reduces serialized snapshot size and therefore its transfer time.

Port r11694 (29aa05e9)

Original commit message:
Implement correct checking for inherited readonliness on assignment.

Removes 6 out of 8 of our remaining unintentional failures on test262.

Also fixes treatment of inherited setters added after the fact.

Specifically:

- In the runtime, when looking for setter callbacks in the prototype chain,
also look for read-only properties. If one is found, reject (exception in
strict mode). If a proxy is found, invoke proper trap.
Note: this folds in the CanPut function from the spec and avoids an extra
lookup over the prototype chain.

- In generated code for stores, insert a test for the maps from the prototype
chain, but only up to the object where the property already exists (which
may be the object itself).
In Hydrogen, if the found property is read-only or not cacheable (e.g. a
proxy), bail out; in a stub, generate an unconditional miss (to get an
exception in strict mode).

- Add test cases and adapt existing test expectations.

This ensures that we don't accidentally throw away getters and/or setters that are still needed. To make sure the bug gets triggered, we have to construct a situation where the map is on the live side of a live->non-live transition. This ensures that the map is passed to ClearNonLiveTransitions.
